Fsbuild-2 Flight Planner

Hi... it appears that aircraft do not follow the glideslope under FSbuild 2.3.1. I fly the standard 737-400 and when the aircraft starts to follow the glideslope it approaches in a staircase manner rather than a smooth linear descent which shows up on the glideslope crosshairs meter. Is there a reason for this or am I doing something wrong.

Thanks

Hi.. I have made a horrible mistake, the problem is not with FSbuild but with FSNavigator where the
problem lies. FSbuild is a great program indeed. I am very sorry for the mixup.
